Delayed Start

I hope this does not sound too dumb a question to the gurus who make up this forum. I just bought a 2001 Z71 tahoe and 95% of the time, it never starts on the first try. I have to try twice to get it to start. As though there is some kind of fuel flow problem. The part that gets me thinking is most of the time, you turn the ignition once and then turn it again, it starts immediately. I dont have to hold it for a couple of secs on the first turn.

Turning the ignition twice gives better results than trying to gas it during the start...

is there something wrong or going back to the basics, is there 'way' to start the tahoe. I am sure no manufacturer is going to make a car that has to be cranked twice to get it to start ( just in case someone has an argument that it hapens becos its cold.

any thoughts or am i doing something wrong

I have a 2000 LS doing the same thing. It turns and turns but has a much delayed ignition. Someone HELP? It seems to do better when it is cold. But once it gets to operationg temp this problem starts until the next day. Then the process starts allover again.

My 86 S10 2.8 and my 94 5.7 Blazer does the same winter and summer, its either the TBI or ignition I think. I havent figured it out till this day... its like there is no spark during the first 4 seconds of cranking....

Check fuel pressure. Most gm vehicles need to have 60 to 62 lbs of pressure when the switch is on, engine off. I had a tahoe with 58 lbs and it took a long time to crank.
